The themal conductivity and electrical resistivity of beryllium at low temperatures are analyzed. From existing data on the effect of reactor irradiation on the electrical resistivity of beryllium, the effect of reactor irradiation at low temperatures on the thermal conductivity is predicted. The arguments show that a reactor exposure of 10/sup 19/ nvt (fast) should decrease the thermal conductivity of beryllium by approximately 0.04 watt/cm/ deg K at temperatures of 20 to 30 deg K. This is measurable but is probably unimportant in practice. High- and low-purity beryllium should be affected similarly. Warming the beryllium to 250 deg K should cause rapid and complete annealing of the radiation-induced change of thermal conductivity. (auth)
